Was prescribed 30 mg Cymbalta for severe fibromyalgia, 30 mg once daily almost immediately stopped my fibro but headache and nausea made it not worth the effort. 2nd attempt 6 months later, I opened the capsules and poured out half the contents again it stopped the severe fibro but headache/nausea after two weeks made me stop taking it. Today I took a whole 30 mg Cymbalta and fibro pain diminished immediately but I intend to take this pill only once a week and see if it will work this way for me. Anyone else had results taking this med this way. My body just cant handle the day to day dosage.
